Re: Replication integrity tool/script

["Michael R. Gettes" <gettes@xxxxxxxxx>]

Given your scenario - if you did a restore then you would get an error message of something like

NSMMReplicationPlugin - agmt="cn=master-t01-to-master-t02" (ldap-master-t02:389): Replica has a different generation ID than the local data.

Yes, I just did this.  Then you would want to conduct an online initialization to bring the replica back into sync.  Given this, all you need to do is monitor that replication is working.  Under normal operations you won't have a problem.   If you start doing exceptional things like mucking directly with the DB file, then this is how you might get into the trouble you describe and the solution is to re-init the replica.

i hope this helps.

Hello,

Thanks for the link, but this not solve my problem. Here is an example of what I do and want I'm specting.

I have 2 servers in multi-master replication A<---->B

Imagine that I have a mismatch in my directory server for some reason (backup restored just in one server, missing change log, or whatever) and server A has 25 users and B has 28 users. But I didn't notice. 
I'm keep working adding users and groups to the LDAP and replication is working well. When I add users to server A they are replicated correctly in server B and vice versa. If i check repl-monitor.pl, it shows me that everyting is OK and the changes made after "the problem" are correctly sincronized, but I've still a mismatch.

Is there any way to check that?

Thanks & Regards.

Hello,

I'm configuring an environment with multi-master replication.

ds - 1.2.10
OS - CentOS release 6.2 (Final)

I'm wondering if there is any tool to check the integrity of both servers, I mean, some tool or script that checks if both servers are exactly the same or if there is some mismatch, just to be sure that replication is working well and we are not missing anything in the process.

Thanks.
